Restore RPC HTTP keepalives to default.

Browse Source 
This avoids a regression for issues like #334 where high speed
 repeated connections eventually run the HTTP client out of
 sockets because all of theirs end up in time_wait.

Maybe the trade-off here is suboptimal, but if both choices will
 fail then we prefer fewer changes until the root cause is solved.
